alpha2 Posted March 31, 2018 Report Posted March 31, 2018 Heinlein = best book, Grok? I've read them all again, since I retired in December. And, all the Sherlock Holms, and a lot of others from the wayback machine. Quote So much leather...so little time.

It is flying into a 10 knot headwind. Then, it flies back to point A at 100 knots airspeed, with a 10 knot tailwind. Will it make up the time it lost flying into the headwind, when it returns with the tailwind? yes , although the air speed is the same, the ground speed is different; going A-B the ground speed is 90 knts, going from B-A the ground speed is 110 knts. T'was one of the first basic questions at navigators classes in RAF. Then it got more and more complicated; air pressure at various heights, different cross winds, fuel consumption of a Buccaneer S2B in lbs per minute. Got through it all.

No, but its why an aeroplane can take off from a ship; take a WW2 type, nominal take off speed was around 70 to 80 knts air speed. An aircraft carrier steams into wind at 20 knts, wind speed is 15 knts = 35 knts along the deck, WW2 fighter just needs to accelerate to ship deck speed of 45 knts to get to take off speed of 80 knts a/s Edited April 1, 2018 by fredk Quote Al speling misteaks aer all mi own werk..

Members LumpenDoodle2 Posted April 2, 2018 Members Report Posted April 2, 2018 Agree, ‘time enough for love’, but ‘Behold the Man’ (Michael Moorcock, not my fave writer), is apt for this time of year.
